Not sure this belongs here, but I thought I'd ask: How should I come to an understanding of an optimal weld sequence for a weld robot that welds a physical item on a revolving carousel (the gray T depicted)?
Ok, so the green points need to be welded in the horizontal position (eight on each side), i.e. 180 and 0/360 position (it is currently in the 270 position). The pink points need to be welded in a 0-15% position in the direction indicated. There is no welding from below, i.e., the downward facing pink arrows need to be welded in a downward orientation, and then flipped to weld the other side. In this depiction there are two sides, downward pink arrows can all be access in the 270 position which it currently is in, upward facing arrows need to be rotated to 90 position. The robot can reach the pink arrows in the back in both these positions. The pink arrows all need what is called a "root pass", and need to cool for at least 10 seconds because they also need a "fillet cover" which if done one after the other too fast can cause imperfections. So all eight pink welds have a root and a cover that need to be staggered by at least 10 seconds. The idea here is to limit the travel on the robot, reduce the number of rotations of the carousel, and reduce the time it takes to weld the whole assembly. The depiction is not to scale, the cylinder with the hangman is the robot in its home position.
So, you can ask questions like if I go from home and start on the left downward pink on robot side and rotate to 360 weld out all the green, then weld the right downward pink on robot side would it be the same if I weld both pink downward robot side then all green, and then move on to upward pink at 90 by that time downward pink will be cool should I rotate back to 270 to cover or should I continue to the other side. I don't know, I'm just trying to formula one this so it's as fast as possible. Any thoughts?
Also, at the end it will rotate back to 270 to flip to the other side to be stripped. That is, the carousel is on a carousel.
I was hoping this was the kind of thing that didn't require dimension and could be reduced to graph or something.
